Doorman rears are still the standard? Just be sure to get the China ones?

Too all!!!!!!!!! Very Important Info!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The Dorman ones that come with the black wheel studs which I think is all you can get now do not take either of the Miata sized wheel studs. They do take Mitsubishi sized wheel studs. The knurl diameter is slightly smaller than the larger of the two Miata sizes.

Confirmed. My Dormans came from Amazon. I found this out the hard way two weeks ago while trying to press in some ARP 100-7720 studs. Ended up reusing my old 1990 hubs and pressed in some ARP 7719's instead.

I'm finally getting around to doing my hubs this year. I pulled the rear hub flanges out of storage (bought them late 2014) and decided to check them after seeing bbundy's comment on the knurl size being off.

Hubs are Dorman 930-550 that I got off Amazon, the knurl diameter of the stud I removed is ~.560-562 and the diameter on the flange is ~.559.

That seems very big. I measured the OEM hole last night at .501". And the ARP studs are .507". I just got F-body studs to try out, and those are .509"

.560 is the Mitsubishi stud. OEM 90-93 is .501, but nobody should be putting original 90-93 hubs back on their car. All the replacements I've bought from Mazda have had ~.575 studs in them, which is the larger 94-05 size.

Ordered two Timken 510003 bearings off Amazon today. Are new seals and retaining clips required with these bearings?

Thanks! I'm shocked RockAuto is cheaper than Amazon for these.

I love rockauto. I replaced my upper ball joints and rear hubs, and rebuilt rear calipers, all for pretty cheap.

How appropriate that I came across this thread today! I replaced all four corners in the past month (May 2106) as part of the turbo build on my 243,000(+) mile NA chassis. It would be truly frightening to have this happen during vigorous street driving.

I can confirm this and I wish I had seen this thread prior to buying the Dorman 930-550 hubs. I kept them around too long to return them, so I'll put them on my other 93LE. The ONLY reason this was an issue for me was because I went to the ARP extended lugs on all four corners.

Oh ****. I have new dorman rear hubs and the machine shop just pressed the ARP studs through. No mention if they where too tight. Scrap them or run them?

Snot just came out. And whiskey.

Yeah, that's scary. Over 100mph and didn't tumble.
Kiss your wife, kids, dog, and cat.
If you have none of the above you should kiss someone else's. And call your mom. She misses you. And say a prayer of thanks. And pour one out for a homey who wasn't as fortunate. And ask that girl out you think is above your level. And take some time to just watch a sunset. And take a kid fishing that doesn't have a daddy. And bring something nice to an old widow who doesn't get many visitors. And adopt an older cat who doesn't have a chance. And feed some squirrels because they are bushy tailed rats.

Yeah, I've thanked my lucky stars every day for the last four months. Probably should start playing the lottery.

Ok, now I'm freaked out. Is it the hub or a bearing failure? I have replaced the bearings on my 95, but not the actual hub.
